Final project | Coursera

Question 1

To answer the following questions you have to analyse dataset flags.csv. You can either install Anaconda to your local computer, download file flags.csv from Course resources, put it into your Jupyter working folder (for example, using Jupyter upload feature) and analyse locally, or just use our Final Project Lab — everything is ready here.

First of all, you have to read dataset using pd.read_csv and save the resulting dataframe in some variable.

How many variables are in dataset?

Question 8

I selected a flag randomly (all flags have equal probabilities). Consider two events: $A$ : 'this flag has no circles' and $B$ : 'this flag has no bars'. Find $P(A\mid B)$ . Enter proper fraction (e.g. 12/13).

Hint: you can use pd.crosstab() to get a table of co-occurrences of variables circles and bars. Arguments of this function are two columns of your dataframe.
